BRICK-'KILN.

Patented June 30, 1908.

Application filed July 9, 1907; Serial No. 382,836.

To all whom it may concern:

Be it known that I, ERNEST R. MeKIs SICK, a citizen of the United States, residing at Adel, in the county of Dallas and State of Iowa, have invented a new and useful Brick- Kiln, of which the following is a specification.

This invention relates to brick kilns, and has for its principal object to provide means whereby the waste heat of one or more kilns may be utilized in the production of steam which may be then employed for any ordinary pur ose, such as the drying of freshly stacked ilns, or for the operation of machinery.

A further object of the invention is to provide a steam boiler and a plurality of manifolds or heating coils connected thereto, the manifolds being so arranged as to be subjected to the high temperature of the prod nets of combustion as they pass from the burning kilns.

A still further object of the invention is to provide a novel form of kiln and to so arrange and construct the kiln manifolds as to permit of ready cleaning and repairs.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the s irit or sacrificing any of the advantages o the invention.

In the accompanying drawings :Figure 1 is a perspective view, partly in the nature of a diagram, showing a boiler and heating manifolds arranged and connected in accordance with the invention. Fig. 2 is a Fig. 3 is a sectional plan view of the same. Fig. 4 is a vertical section of the lower portion of the kiln on the line a e of Fig. 3.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The twin boilers 10 may be of any ordinary construction and are arranged within a suitable furnace 11. The boilers are supplied with water from a feed pump pipe 15 which is connected by valved branches 16 to the lower portion of each boiler. The steam domes 17 are coupled to a pipe 18 from which leads a supply pipe 19 to the engine,

brick pressing machine, or other device to be operated. The boiler or boilers are arranged adjacent to a number of kilns 20, and each of these kilns is arranged to contain a manifold 21, provision being made for coupling the manifolds individually to the boiler, so that those in empty kilns may be cut out.

In constructing the kiln, a trench 24 is formed diametrically across the bottom of the kiln, and from the central portion of this trench leads the escape ilue 25 to the stack. All of the products of combustion after pass ing through the bricks are directed into the trough 24, and thence pass out through the escape flue 25.

On the floor of the kiln are arranged parallel rows 25 formed of large brick, and on these is placed a false flooring 26, the 'llooriug being formed of bricks each provided near one edge with a recess 27, so that a perforated 'l'lOOl is formed, the perforations being evenly distributed throughout the entire area of the kiln.

The products of combustion enter the kiln through a number of fines 28 and pass upward to the top of the kiln, and thence are deflected down through the brick to be burned, and passing through the recesses or perforations 27 will flow into the channels between the rows 25. As all of these channels communicate with the trench 24, the entire volume of the products of combustion will be compelled to enter the trench and will be evenly distributed throughout the length of said trench by reason of the numerous channels through which the burn ing gases must flow.

Arranged in each trench is a manifold 21, each manifold comprising a pair of vertical headers 2930 connected by two rows of pipes or tubes 31. The water to be con- -verted into steam enters the lower portion of the header 30 through a pipe 32 and passes out in the form of steam through a pipe 33 leading from the top of the header 29. In order to assist the flow, the bottom of the entrance header 30 is arranged a trifle below the bottom of the discharge header 29, so that all of the tubes 21 will slightly incline up'ward toward the discharging manifold, in order not to impede the circulation.

Connected With the lower part of the boiler or boilers, preferably by the valved branches 16, is a pipe which leads to all of the kilns, and is connected to the separate pipes 32, and each of the latter has a valve 36 for the purpose of cutting out the manifold of an idle kiln, while the manifolds of all of the active kilns may be individually connected up with the boiler.

The steam discharges through the pipe 33 having a valve 34 and connected in each pipe is a water gage 38. The upper ends of these pipes are connected to a pipe 40 that leads to the pipe 18, and is thus placed in communication with the steam dome or domes.

In operation the system is sup lied with water until the manifolds are fufl and the water has risen in the boiler to the desired level. Fire is than started in the boiler furnace, and the heat from the kilns raises the temperature of the water in the manifolds.

As steam forms in the boiler and in the manifolds, it is drawn off through the pipe 19 to the point of consumption and utilized for any purpose. As the boilers are at a higher level than the manifolds, the latter will be constantly filled with water and there will be no danger of burning out of the manifolds or liability of explosion through lack of Water.

I claim 2-- 1. In apparatus of the class described, a steam boiler, a furnace in which the boiler is arranged, a plurality of brick kilns, each having an escape passage, for the products of combustion from the kiln, a manifold arranged in each of the passages beneath the floor of the kiln, a water circulating pipe extending from the water space of the boiler to all of the manifolds permitting the former to keep the latter constantly supplied with water, a valved branch leading from the wa ter pipe to each manifold to permit independent connection and disconnection of the atter, and a separate steam pipe leading from each of the manifolds and connected to the boiler, each steam pipe having a separate controlling valve.

2. In apparatus of the class described, a brick kiln having a trench extending diametrically across and below its floor, the bottom of the trench being inclined, a manifold arranged in the trench and comprising a pair of end headers, and connecting pipe, one of said headers being arranged slightly below the other, and the connecting pipes being inclined between the headers, bricks arranged on the floor and disposed in paralj lel rows to form a large number of trans versely extending channels, all of which communicate with the trench, recessed bricks mounted on the rows of bricks and forming a perforated false bottom for the kiln, an escape flue leading from the trench, a steam boiler, a water pipe connecting the water space of the boiler to the lowermost header, and a steam pipe connecting the uppermost header to the steam space of the boiler.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
